Air quality gains insufficient

| Thursday, Aug. 18, 2016, 8:55 p.m.

The article, “Ozone Action Days decline in Pittsburgh area with drop in pollutants” tries to paint a pretty picture but reality is hazier. Allegheny and several surrounding counties are recording ozone levels above the federal standard of 70 parts per billion (ppb) set by the Environmental Protection Agency. More troubling: The EPA predicts Allegheny County may be one of just a few counties nationwide not able to meet this standard far into the future. Even more disconcerting is that the new EPA standard isn't as protective of health as it should be.

Many medical professional groups, such as the American Thoracic Society, recommend an even lower, more protective standard of 60 ppb.

In addition, action days are only called when the air quality is forecast to be above the federal standard of 70 ppb. But vulnerable populations like asthmatics, children, the elderly and those with heart disease could experience negative health effects at lower levels.

Progress is being made, but efforts to clean the air must increase so that all citizens can breathe easy.

TribLIVE commenting policy

You are solely responsible for your comments and by using you agree to our Terms of Service.

We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.

While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.

We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers

We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.

We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.

We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.

We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
